摘　　要：本文根据1983年5月至1984年5月台湾海峡中、北部海洋综合调查资料,研究了该区棘皮动物的分布。结果表明,该区棘皮动物83种,初步鉴定到种的有61种;以亚热带种占优势,在组成上更接近于南海,与南海的共有种占62.7%;全区棘皮动物生物量6.18g/m^2,均较南海和东海的高;细颗粒沉积区中生物量较高,而粗颗粒沉积区种类多样性较高。This paper in based on echinoderm samples collected in the comperphensive investigation of the Taiwan Strait (24°30′～26°00′N, 118°40′～121°00′E) in the period of May 1983 to May 1984.Of the 83 species of echinoderms found in the region investigated, 61 species have been indentified. In the species composition, the subtropical species are dominant, the composition of echinoderms species is found close to that in the South China Sea, sharing 62.7% common species. The echinoderm biomass in this area (6.18g/m^2) is higher than that in the South China Sea and the East China Sea. The echinoderm biomass in the fine sediments area in higher, the species diversity in the coarse sediments area is higher.
